DOOR-LOCK TRIMMING.

Specification of Letters Patent.

Patented Apr. 23, 1912.

To all whom it may concern:

Be it known that we, HENRY Gr. VoIsHT and NORMAN B. Hum), citizens, of the United States, residing at New Britain, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Door-Lock Trimmings, of which the following is a full, clear, and exact description.

This invention relates to improvements in door lock trimmings.-

The object of the present invention is to provide an improved trimming to be used on so-called sanitary doors, the purpose of said trimming being to make a proper finish for a keyhole passage and for knob passages which will lie substantially flush with the door so as to avoid corners and recesses in which dirt and dust can accumulate.

In the drawings, Figure 1 is a side elevation of a. part of a door, said view being partly in section, illustrating our invention as applied thereto. Fig. 2 is a vertical section in the plane of the knob in the keyhole, certain parts being in elevation. Figs. 3, 4, 5 and 6 each illustrate details of construction.

1 represents a door.

2 represents a knob.

3 represents a key.

\Ve will first describe the rose plate or trimming for the knob shank. This rose plate or trimming comprises two members -5. The member 5 is circular in form, having a central threaded recess at its outer side arranged to receive the screw-threaded end of the member 4. In the bottom of the recess inthe member 5 and piercing the side wall thereof at as manypoints as desired (four being shown here) are passages in which are located spurs 66. The inner end of the member 4 is preferably beveled, as shown, and arranged to engage the rear ends of the spurs 6-6, the bevel being indicated at 7 As will now be seen, a recess is formed in the door concentricwith the axis of the knob 3, said recess being of a depth and size appropriate to'receive the member 5 flush with the surface of the door 1. The member 5 is then put in place. The spurs 6-6 are then entered and forced radially so as to project into the material of the door 1. These spurs may be forced radially in any desired manner, as by screwing in the member 4 so that the bevel 7 will engage with the rear ends of the spurs and force them outwardly. When the parts are thus assembled, it will be seen that the surface I,

of the door 1s substantially flush save for the projection of the member 4: of the trimming. The particular form of retainers may be modified in a variety of ways, the particular form of spur retainers 6-* shown being one improved form. The keyhole trimming may be in the main similarly constructed and applied, said trimming coinprising the outer member 5 and the mner member 4 and the spur members 6-6, as inthe first instance. The inner member 1* may be provided with a suitable passage best adapted to receive a key, instead of a knob spindle as in the first instance; for example, said'inner member may have a keyhole passage of conventional outline, such as shown in Fig. 4.. In both instances it will be seen that the trimming comprises two main parts, one arranged to interlock as by screw-threads with the other, both of said parts having a suitable passage for the particular instrumentality to be employed therewith, be it a key or a knob spindle. In addition to the two elements re ferred to, the trimming includes movable interlocking devices or means arranged to be forced outwardly or radially into intimate engagement and binding contact with the material of the door so that when the two members are secured in position, the trimming will be complete and will present a severely plain yet handsome appearance which, from a practical standpoint, has a decided advantage over any ornamental trimming which stands wholly above the surface of the door, providing grooves or corners in which dirt may accumulate and from which it is exceedingly difficult to remove such accumulation.

What we claim is:

1. In a door lock trimming of the character described, one member arranged to be sunken in a recess in the surface of a door, a coact-ing member with means for securing the same to the first mentioned member, holding means carried by the first mentioned member and movable outwardly from the edge thereof to engage with the material of the door to hold the first mentioned member in place.

2. In a door lock trimming of the character described, one member arranged to be sunken in a recess in the surface of a door, a coacting member with means for securing the same to the first mentioned member, holding means carried by the first mention ed member and movable outwardly from the edge thereof to engage With the material of the door to hold the first mentioned member in place, said second member coacting With said holding means to hold the same in their operative position When the parts are assembled.

3. In a door lock trimming of the character described, one member arranged to be sunken in the surface of a door, a threaded recess in the outer end of said member, perforations in the side Walls of said member, holding devices standing in said perforations and arranged to be moved laterally relatively to the axis of said member, a second member threaded to fit Within the threaded recess of said first mentioned member, and arranged to engage said holding devices to hold the latter in their operative positions.

4L. In a door lock trimming of the character described, one member arranged to be sunken in the surface of a door, a threaded recess in. the outer end of said member, perforations in the side Walls of said member, holding devices standing in said perforations and arranged to be moved laterally relatively to the axis of said member, a second member threaded to fit Within the threaded recess of said first mentioned member, and arranged to engage said holding devices to hold the latter in their operative positions, said second member being constructcd to force said holding devices into operative position.
